Application filed August 14, 1905. Serial No. 274,190.

To @ZZ whom it may con/cern:

Be it' known that '1, JOHN A. JOHNSON, citizen of the United States,residing' at AFilinainac, in the county of Pulaski and lState ofindiana, have invented certain new and useful Improvements inMoldFilling Devices, of which the followin isv a specification.

This inventionre ates to a device employed in connection with molds; andthe object of the invention is4 to direct material to be formed into'molded articles into the molds and also to remove the surplus materialthat r remains after the molds have been filled and subsequentlytoreconvey and deposit said surplus material into the succeeding molds.Vlith this device the dissemination of the material is not onlyprevented, but also the rehandling thereof.

rThis invention is particularly applicable on my invention that formsthe subject-matter of application for patent on "Mold for formingbuilding-blocks 'liledin the United States PatentrOiiice on March 16,1905, Serial No. 250,456. l A device embodying` the several partswhereby the advantages soiight'are attained will first bemore-particularly described in the annexed spec'iication and the novelfeatures then pointed out in the claims.

Referring to the accompanying drawings, which 'are madev a part hereof,and on which similar numerals of reference indicate similar parts,Figure l is a top or plan view of one end of the mold-iilling device;Fig. i2, a crosssection of the same as seen from the dotted line 2 2 inFig. 1. Fig. 3 is a front elevation of the device in which the centralportion is broken away. Fig. 4 is a cross-section ofthe device as seenfrom the dotted line 4 4 in Fig. 1 and shows the parts in openedpositions.

In the drawings, l is a rectangular-shaped .base-frame, preferablycomposed of metal,

and forms the support for the pallet-board 2, V

ports the mold 3, an upper-'frame that carries the filling device, asvwell as said filling device. The base 1, pallet-board 2, and uper frameare similarly constructed as shown and described in my formerapplication above mentioned, and no further reference will be made tothem. except incidentally with the parts forming the subject-matter ofthis invention.

A second and upper frame, comprising the on whichthe molding is done,and also supmembers 5 and 6, which conform to the out-i line of the base1, is suitably hinged to the latter by means ofthe hinges 7. `The endsof the member 5 of the upper frame are bent at right angle to the mainbody and form the ends 8 of said frame. These end-forming members S areprovided with the hooks 9, which engage and form seats for the pivot'-ally mounted straps l0, mounted on the member '6 of the upper frame,and' form locks for securing the two parts of the upper frain'etogether. frame incloses the mold, and the latter is securely held whilethe molding operation is in progress. Y

Secured to by means of the bolts 12and moving -with the member 5 of theupper frame is a hoppencarrying frame that comprises the side* members14 and the'ty'inge cleats l5. 'llie members 14 are provided with theguideways l7, that receive the slides 1S, secured to the hopperQO. Thehopper is a rectangular-shaped box, minus a bottom, having anadjustably-mounted board that forms the head therefor. The hopper Z0 isso positioned in the guideways 17 that the lower end thereof will slideover and in contact with the top ofthe mold 3 and remove the surplusmaterial from the mold when said hopper is moved horizontally from overthe former. The bottom of the hopper 20 is practically open except atintervals where narrow cleats Z6 passvtransversely thereof. These cleatsare intended to close-the spaces 25, that exist between the individualmolds, which spaces are necessary to permit the molds to bev expanded tofree the molded articles, and thus prevent the dissemination of thematerial lthrough 4said'spaces when the hopper is moved over the mold.

As previously stated, the'l head 30 of the hopper is adjustablyinbunted,`so that it may be moved into any inclined position, and formsa seat for mounting the cutting-plates 3l. These plates remove thesurplus material from the molds 3 and are adjustably secured by means ofthe screws 32,so that they may be adjusted to compensate Vfor the wear.

The adjustability of the head 3() percan'be materially increased whendesired.

Experience has proven that the more dense' the material the moreinclination from the IOO . hopper 20 perpendicular should be impartedthe cutting-plates 3l to lessen the cutting resistance.

The adjustable member or head 30 vof the hopper is provided with thespring-metal trowels 34, which are drawn over the eX- posed faces of themolded articles from which the cutting-plates removed the surplusmaterial, leaving a smooth and finished surface. The resiliency of the4trowels keeps them in contact Vwith the molded articles while the ismoved, and their flexibility permits'them to be bent -to conform to theangle into which the head may be placed.

It' will be noted that the hopper-frame is provided with a floor 40, onwhich the open bottom of the hopper slides, so that when the hopper isdrawn over said floor the latter will catch and retain the surplusmaterial carried by said hopper. On the succeeding movement of thehopper the surplus material is removed fromthe'floor 40 and is dumpedintoy the succeeding empty mold.

, When the hopper 20 is moved into the position shown in Fig. 2 straps10 are removed from the hooks 9, that form the locks for securing thetwo parts of the u per frame together, when the member 5 of t ewupperframe is allowed to swing backward into vertical'` position and carry1n`the hopper-frame and hopper with it. The ront member 6 of the upperframe may also be swung backward, (see Fig 4,)\ leaving the way for theremoval of the mold 3 free'from obstruction.A The pallet-board, with themolded articles, may another board and mold substituted, when theoperation as heretofore set forth is re-l Having thus fully describedmysaid invention, what I desire to secure by Letters Patent, is- Y 1.
